Paul J. Limburg, MD, MPH, AGAF, Editor Dan A. Dixon, PhD, Editor Gastrointestinal (GI) neoplasias present a substantial challenge to global public health, with recent data demonstrating that esophageal, gastric,…
Humans are host to complex microbial communities previously termed normal flora and largely overlooked. However, resident microbes contribute to both health and disease. Investigators are beginning to define microbes that…
Cancer is fundamentally a genetic disease caused by mutational or epigenetic alterations in DNA. There has been a remarkable expansion of the molecular understanding of colonic carcinogenesis in the last…
The first 15 years of management of gastrointestinal stromal tumor (GIST) have led to 3 lines of therapy for metastatic disease: imatinib, sunitinib, and regorafenib. In the adjuvant setting, imatinib is…
Although almost all gastrointestinal cancers develop from sporadic genomic events, approximately 5% arise from germline mutations in genes associated with cancer predisposition. The number of these genes continues to increase….
Emerging molecular tools promise to extend the diagnostic reach of the endoscopist and open doors to population screening for gastrointestinal (GI) cancers. This review briefly addresses biological considerations in marker…
Neuroendocrine tumors are increasingly diagnosed, either incidentally as part of screening processes, or for symptoms, which have commonly been mistaken for other disorders initially. The diagnostic workup to characterize tumor…
Small bowel adenocarcinomas (SBAs) are rare tumors, but their incidence is increasing. The most common primary location is the duodenum. Even though SBAs are more often sporadic, some diseases are…
Pancreatic cancer is now the third leading cause of cancer related deaths in the United States, yet advances in treatment options have been minimal over the past decade. In this…
Gastric cancer (GC) is third leading cause of cancer-related death. Only 28.3% of new GC cases survive more than 5 years. Although incidence has declined in the United States, an…
